'LOCKIN G DEVICE.

To all whom it may concern Be. it known that we, WALLIE R. BOONE andCHESTER A. INA'rsoN, citizens of the United States, residing at Crews,in the county of Runnels and State of Texas, have invented certain newand useful Improvements in Looking Devices, of which the following is aspecification.

v This invention relates to improvements 'in locking devices. I

The object of the invention is to provide a lockin device for coincontrolled receptacles and involves a particular mechanism for holdingand delivering a key and whereby a lock, a controlling apparatus, a keyfastenin device, and a coin receptacle are combine in a single casing."Another feature resides in the construction of the key and the keyfastening device whereby the key is fastened in the look after beinginserted and cannot be removed until a releasing plunger is inserted inthe key.

A still further object of the invention is to provide a device of the'character destrong, durable, efiicient,

construct and maintain, also one in which the several parts will not belikely to get out of working order.

With the above and other objects in view the invention has relation tocertain novel features of construction and operation, an example ofwhich is described in the following specification and illustrated in theaccompanying drawings, wherein:

Figure 1 is a vertical sectional view of the device, Fig. 2 is an endelevation, Fig.-3is a front elevation, and Fig. 4 is a detail insection'of the key and key fastening device. In the drawings the numeral1 designates a casing which is suitably secured to the door of a storagecabinet such as is used in public places for storing hats, coats and theAt one side of the casing a vertical ceive a key 3. At the lower end ofthe tube is a hinged closure 4 held normally closed by engagement with aspring latch 5 secured to the side of the casing. The tube is open atits upper end so that the key may be dropped'thereinto and fell upon astop lever 6 which is pivoted at its central portion in the casing andprojects into the tube through an opening in the side of the same.

The inner end of the lever 6 has a hook 7 which counter-balances thelever to the extent of swingingthe opposite end into the tube and in thepath of the key. At the opposite side of the casing a verticalcoin tube8 is located and terminates some dis tance from the bottom of thecasing. The lower end of the tube 8 is closed and a coin drawer 9 isfitted thereinto from the side of the casing. This drawer has a suitablepermutation lock arrangement whereby it may be fastened in position.

A. coin or check drop ed in the upper end of the tube 8 will in fal ingstrike and swing downward the end of a tripping lever 10, after whichsaid coin falls into the drawer 9. The lever 10 is bent at angle so thatone end will normally project through an opening in the tube 8 andincline downward, while the other end will normally extend horizontallyacross the casing so that a hook 11 on its end may engage the hook 7 0fthe lever 6 and hold the latter and the key 3 in position. When the coinswings the tripping lever, the levers assume the position shown indotted lines in Fig. land the key drops down upon the closure' l. Toobtain the key it'is merely necessaryto release and open the closure.

In the lower port-ion of the casing a suitable r bdlt 12 which extendstransversely of the casing under the tube 8, is arranged to projectthrough the side of the casin and engage in a keeper 14 secured to thecabinet. In the front wall of the casing a key-hole 15 is provided andthrough which the key 3 may be inserted to engage and operate the bolt12. One of the particular features of the in vention is the constructionof the key and a means whereby the key after being inserted through thekey-hole cannot be removed except by an attendant having a special toolfor releasing the key. prevents persons from carrying away the key.

posite the key-hole a pocket or rearwardly extending housing 16 isprovided. In this pocket a grapple or clamp member 17 is secured. Thegrapple is preferably formed of spring metal and provided with a. pairof outwardly flared opposed tongues-within wardly directed lugs 18 asshown in Fig. 4.

or clmws, rnxAs, asszeuons or ONE- In the rear wall of-thecasingdirectly op- This arrangement spring pressed disk 19 is arrangedin the grapple so that upon being forced inward it will spread thetongues apart.

The key 3 has a central longitudinal passageSO of such diameter as tofreely receive a plunger 31. That end of the key which enters the casinghas a beveled portion 32 .adjacent which a circumferential groove 33 isformed in. the key. When the key is inse'rted in the casing the beveledend will engage the lugs 18 and spring them apart. The lugs ride oil ofthe beveled portion and spring intothe groove thus holding the keyagainst withdrawal. While the bolt 12 may be operated to gainentrance-to the cabinet,

i the key cannot beremoved from the casing.

To remove the key from the casing the plunger 31 is inserted through thepassage and engaged with a stud 34 projecting forwardfrom the center ofthe disk.19. By

pressing inward on the plunger the disk is forced inward and the grapplespread apart sofas to release the keyl The key is then deposited in thetube 2 and the apparatus is ready for another operation. When thecabinet is not in use the bolt 12 is withdrawn so that the door to whichthe casing isattached may be opened. After articles are placed in thecabinet and the door closed the bolt 12 is projected into the keeper 14by akey-knob 35 which is turned.

The bolt Pi'S locked in the usual way. The cabinet cannot be unlockeduntil a coin or check is deposited in the tube 8 and the key 3 obtained.

What we claim, is: .1. In a check controlled apparatus, a casing, keyadapted to enter the casing and provided with a passage, a springfastening member secured in the casing in position to receive the end ofthe key and provided with key engaging parts, and a releasing deviceadapted to enter the passage of the key.

2. In a check controlled apparatus, a casing having a pocket, a grapplesecured in the pocket and provided with key engaging members, areleasing member arranged in the grapple, a key having a passage andprovided with a circumferential groove located to receive the members ofthe grapple, and a plunger adapted to pass through the passage of thekey.

3. In a check controlled apparatus, a casing having a key-hole and apocket opposite the key-hole, a spring grapple secured in the pocket anddirected toward the key-hole of the casing,-a spring pressed diskmounted in the grapple, opposed lugs provided on the grapple, a keyhaving a beveled end and provided with a circumferential groove adjacentthe said end, said key also having a central longitudinal passageextending therethrough, and plunger adapted to pass through the passageof the key, the lugs of the grapple being in the path of the beveled endof the key, the disk being in the path of the plunger.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
